Hmmm...

I really am a total neophyte in terms of linux & in terms of anything involving terminal / command line programming.

I tried setting up mySQL using two sets of instructions, slightly different from each other...

http://www.debuntu.org/how-to-create-a- ... -to-a-user

http://amarok.kde.org/wiki/MySQL_HowTo

neither one of them worked - I mean, Amarok still gives me an error message when I try setting it to work with mySQL (in "configure amarok").

a basic question: if I did all this stuff in the terminal, did I completely screw up my internal operating system? 

is there a way to tell?  Or is there a way I can just instantly un-do everything I did yesterday?

Also - I looked at the ubuntu guide to terminal, and it did not have the answer to this question (unless I missed it)

when I am in the command line, and the instruction gives a semi colon at the end of the line, like this

$ mysql -u root
set password for root@localhost = password('xxxxxxx');
flush privileges;
quit;


should I actually type in the semi colon?  or is that just an instruction to hit the return key or something?

also, when the instructions give four lines of stuff (like above), do I hit return at the end of each of those lines...?

am totally confused - I guess if worst comes to worst, I can erase the whole drive and re-install the entire ubuntu system... start all over again....

thanks!
